Describe the bug

Using a Velocity-Proxy in front of multiple SpongeVanilla-1.19.2 servers with ip-forwarding kicks players after they switched servers. (no mods or plugins used)

How to reproduce

• setup a new velocity-server (Velocity 3.1.2-SNAPSHOT (git-7d77bfb5-b184) in my case)
• setup two sponge servers
• enable ip-forwarding in sponges configs and setup the modern (or legacy) protocols in sponge and velocity
• start all servers and join via the velocity proxy
• chat something random
• switch servers (/server <server>)
• chat something random again

What i would expect to happen Chat message is being sent, possibly with no validation like in offline-mode servers.

What actually happens Player is being kicked with the sponge-server log saying:

[14:10:25] [Netty Server IO #4/WARN]: Failed to validate message from TBlueF, reasons: unknown message
[14:10:25] [Server thread/INFO]: TBlueF lost connection: Chat message validation failure
[14:10:25] [Server thread/INFO]: TBlueF left the game
